Little-known Gulf Manta Rays Affected by Oil Spill?

Gulf Manta rays' daily lives might be interrupted and altered. With the five million barrels of oil that were burned and released into the ocean, the 'cleaning stations' where small fish clean out their gills, might be infected with oil, according to marine biologist Andrea Marshall of the Mozambique-based Foundation for the Protection of Marine Megafauna. Accoring to Rachel Graham, a shark scientist with the program Ocean Giant's at the Wildlife Conservation's Society, said that these creatures grow to such large sizes by taking sea water in and out through their gills. They also keep tiny creatures such as plankton in their gills.They grow to 20 feet long and could possibly be of their own species, but it is not quite certain. Their gills are quite sensitive to any toxins in the water. The dispersants used to break up the oil can be harmful to the Manta rays, and gills are covered they could suffocate and die due to the lack of oxygen. Because little is known about the Manta rays, it is possible their reproduction or migration in the gulf  can be disrupted, says Mexican marine biologist Silvia Hinojosa Alvarez who is a part of the Mexican Caribbean Manta Project. She also states that little is known of where they give birth, so because of the little bit of information that they do have on the biology of these creatures, they cannot give an accurate prediction of what could happen to them.
This is so sad. Somebody needs to figure out how to help them. This case is similar to the whale sharks predicament. All of these creatures are dying because of the Gulf spill, but what is being done to those responsible for the spill? Something must be done to these irresponsible workers.
